The short version

  • Only OpenBOM has a free tier, so it costs nothing to try first.
  • Each has a real cost: Duro PLM no pricing is published anywhere, so budgeting requires a sales conversation and buyers cannot compare against alternatives without entering a pipeline.; OpenBOM pricing has three axes, editing seats plus data record count plus per-seat CAD add-ins at $25 to $45 each, so the real annual cost is well above the advertised per-seat figure.
  • They diverge on capability: Duro PLM covers Part library, OpenBOM covers Part catalogue.
  • Prices and features above were last checked on 31 August 2026.

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Duro PLM

  • No pricing is published anywhere, so budgeting requires a sales conversation and buyers cannot compare against alternatives without entering a pipeline.
  • Plans are sold in fixed user bands rather than per seat, so hiring an eleventh engineer moves you to the next tier instead of adding one seat.
  • Storage allowances are capped at 25, 50 and 100 GB, which is tight for teams keeping native CAD files rather than only neutral formats.
  • There is no self-hosted or on-premises option, which rules Duro out for defence and some aerospace suppliers with data residency or ITAR handling constraints.
  • Scope stops at engineering data: no requirements management, no quality module and no manufacturing process planning, so it does not replace the systems a company needs at production scale.

OpenBOM

  • Pricing has three axes, editing seats plus data record count plus per-seat CAD add-ins at $25 to $45 each, so the real annual cost is well above the advertised per-seat figure.
  • Paying yearly nearly halves the seat price, from $55 to $30 and $165 to $90, so monthly billing carries an unusually heavy penalty for teams that want flexibility.
  • Change management, revision control and CAD file management are absent from the entry Team plan, so the cheapest tier is a catalogue rather than a working PLM.
  • It lacks the approval workflows, effectivity dating and audit depth that regulated medical and aerospace suppliers need, so companies pursuing ISO 13485 or AS9100 typically migrate away.
  • Record count is metered separately and a large imported part library can push a small team into a higher data tier without adding a single user.

Answered from the vendors’ own pages

Duro PLM: How much does Duro cost?

Duro does not publish prices. Plans are fixed annual subscriptions quoted by sales against a user band, billed Net 30.

OpenBOM: Is OpenBOM free?

There is a genuine free tier limited to 2,000 data records and aimed at non-commercial and educational use. Commercial teams start at $30 per seat per month billed yearly.

Duro PLM: Can I run Duro on my own servers?

No. It is cloud only, which is a hard blocker for organisations with data residency or export control requirements.

OpenBOM: Do I pay for people who only look at BOMs?

No. Read-only users are unlimited and free on every paid plan, which is the main reason the total cost undercuts seat-for-seat PLM tools.

Duro PLM: What happens when we exceed our user band?

You move to the next tier rather than adding individual seats, so growth arrives as a step change in cost.

OpenBOM: Are the CAD add-ins included?

No. They are $25 per seat per month billed yearly, $45 monthly, and require an active Team or Company subscription.

Duro PLM: Is Duro suitable for medical device work?

Its change control is real but the workflow configuration and audit depth are lighter than dedicated regulated-industry PLM, so most ISO 13485 programmes need more.

OpenBOM: Can OpenBOM replace a full PLM?

For a startup, usually yes. For regulated manufacturing needing controlled workflows and full audit trails, no.
